two people were murdered here, jennifer and john longworth. do you believe they were target of this explosion? >> at this time we have no reason to believe that there was an intentional targeting of anyone. jenna: there's also two other names that have come up,, mark leonard, apparently that was the house where the explosion was centered, and they were not home at this time. how are they involved in the investigation? >> i can't speak to that other than what you've stated is accurate, which is that they were residing in the home which was the source of the the explosion. jenna: one of the other things that has been brought up at least in local reports is a white van, a search for a white van in the area, in the neighborhood. apparently, we've heard reports it's been impounded, it's been searched, can you tell us anything about what role this white van may play in this? >> obviously, we had reason to believe that there was a vehicle matching that description in the neighborhood at a relevant time, beyond that i can't speak to anything else rela
